OUTBOARD MOTOR MOUNTING Paul .lay Homan, Napoleon, Ohio Application May26, 1954, Serial No. 432,450

1 Claim. (Cl. 70-58) This invention relates to means for locking thestandard form of outboard motor to the stern of a row-boat or other formof craft adapted for use with motors of this My locking device is soconstructed as to be readily attached to the stern construction of `theboat, and when so attached cannot be removed after locking the motor inplace, without the proper key. A simple and positive means is thusprovided to insure against the possible removal of the outboard motor byunauthorized persons and theft of same.

A novel feature of my device is provided in which the lowering of themotor into place trips the lock and causes immediate and automaticlocking action, the device being adapted to receive diiferent makes ofoutboard motors.

Other objects and advantages of the invention will hereinafter appearand for purposes of illustration, but not of limitation, an embodimentof the invention is shown in the accompanying drawings, in which Figure1 is a partial view of the stern of a boat showing the outboard motorbeing lowered into the locking device;

Figure 2 is an elevation showing the locking device, with Ithe motorlocked in place;

Figure 3 is a section taken on the line 3 3 of Figure 2;

Figure 4 is a top View of the locking device, before locking action hastaken place;

Figure 5 is a section taken on the line 5--5 of Figure 4;

Figure 6 is a top View of the locking device, after the locking actionhas taken place;

Figure 7 is a section taken on the line 7-7 of Figure 6;

Figure 8 is an elevation of the locking member, removed from the casing;and

Figure 9 is a perspective view of the lock tripping element.

Referring to the drawings and particularly Figure l a boat indicatedgenerally at 10 is provided with a substantial stern piece 11 to whichis attached my novel locking means, indicated generally at 12. As shownin Figure l, fthe motor indicated generally at 13 is provided with thecustomary hook form of attaching clamp 14 carrying a plurality ofhorizontally arranged screw-clamping elements 15.

It will be noted that the locking device 12 is provided in its uppersurface with a pair of laterally spaced T-shaped openings 16 and 17,these being adapted to receive the screw clamps and to permit same to belowered into the longitudinally slotted opening 18 and the verticalopening 19, wherein they may be tightened to clamp the motor 13 securelyagainst the stern piece 11 of the boat.

The lowering of the adjacent clamp 15 into the slot 19 moreover causesthe lock to snap into closed position, as will hereinafter be described.

Figure 2 shows in elevation the locking device with the clamps 15 inlocked position, and as shown in Figure 3, my locking device is providedwith a substantial metallic back plate 20 against which the contactmembers 15a of the screw clamps 15, are adapted to exert pressure, thusgripping the stern piece 11 between the plate 20 and the motor attachingclamp 14.

The locking device 12 is permanently Xed to the stern piece of the boatby means of a plurality of screws 21, passing through the back plate 20into the wood thereof, and so positioned that access to the heads of thescrews cannot be had for removal when the device is locked.

It will also be noted in Figure 2 that the length of the opening 18 inthe front panel of the lock 12, permits a variation in the transversespacing of the screw-clamps 15, in order to provide for various types ofoutboard motor clamping means.

Referring to Figures 4, 5, 8 and 9 the locking device is here shown inopen position ready to receive the motor clamps Ithrough the topopenings 16 and 17 in the top horizontal wall of the casing 24. Thelocking slide member 25, individually shown in Figure 8 is adapted toslide within the casing 24, being biased into locking engagement by acoil spring 26, which engages a lug 27 on the casing 24 and a similarlug 28 on the locking member 25.

A locking latch member 29 is secured to the locking slide 25 and isoperated by a key and tumbler controlled cylinder 30. The latch 29 isadapted normally to press a latching slide member 31 upward as biased bya spring 32, a lug 33 being welded to the upper wall of the casing 24 inthe path of the latching member 31, whereby the locking member 25 isheld in open position. An opening 34 in the latch member in thisposition of the slide 25 is aligned with the opening 16 in the casing,and a locking element 35 on the slide is withdrawn from the opening 17in the casing.

The latching member 31 is formed at its lower end with a cut out portionor notch 36 in which an arm 37 on a trigger member 38 is adapted to seatin the open position of the locking device. The trigger 38 is pivoted tothe casing 24 at 39 and is biased to swing upwardly by means of ahair-pin spring 40, which surrounds the pivot 39 and presses upwardly onthe arm 37 of the latching member, as shown in Figure 5.

The trigger member 38 has an upstanding portion 41, which in the openposition of the lock (Figure 5) covers a portion of the slot 19 in thecasing 24. Thus it will be seen that :as the motor 13 is lowered inplace, the screw clamp 15 will strike the portion 41 of the trigger 38.When this takes place, the trigger 38 will be depressed and rotatingabout pivot 39 it will carry with it the latch 31, due to the engagementof the arm 37 with the notch 36.

When the latch 31 has been carried downwardly enough to move it out ofthe path of the lug 33 on the top of the casing, the entire lockingmember 25 will be shifted into locking position by the action of spring26, a stop 43 on the casing 24 limiting the locking movement of thelocking slide 25.

The parts will then be in the positions shown in Figures 2, 6 and 7 withthe clamps 15 locked within the casing by the portions 42 and 35 of thelocking member 25. The parts now cannot be moved to open position due tothe interference of the latch 31 with the lug 33 on the top of thecasing 24. However, if the owner of the key wishes to open the device,he has only to insert the key in the tumbler cylinder 30, rotate same toslide the latch 31 downwardly out of the path of the lug 33, when he canonce more slide the locking member 25 to open position against thepressure of spring 26, by moving the engaged key to the left. As shown,the cylinder 30 projects through a slot in the housing and serves as ahandle for manually shifting the slide 25 to open or unlocked position.

When he has thus pushed the lock open, the latch 31 will once more be onthe left side of the lug 33 and on rotating the key, it will againengage the lug as shown in Figure 5. The key can now be withdrawn andthe lock will stay in open position until tripped by the trigger 38 ashereinbefore described.

An important advantage of the above structure is that it can accommodateoutboard motors of diierent makes and which have different lateralspacing of the clamps 15. In case the spacing of the clamps is greateror less than that of the openings in the casing, the respective clamp isrst inserted into the elongate slot 18 and then shifted oneV way or theother until the other clamp is properly positioned with respect to thevertical casing opening 19 when it can then be dropped into place.

It will be manifest that the structure of the assembly is simple and thenumber of parts is reduced to a minimum so that it can be manufacturedeconomically on a quantity basis. When the motor clamps are installed,the screws 21 which secure the unit to the boat, are covered so thataccess to them cannot be had unless the motor is removed,Y

to the housing, a spring urging said trigger to a position where aportion thereof partially obstructs the other of said openings, alocking slide shiftably mounted in said housing, a spring urging saidlocking slide to a position where portions thereof obstruct theentrances to said openings, a latch member carried on said slide andmovable relative thereto in a direction at right angles to the directionof movement of the slide,a stop in the housing against one side of whichsaid latching member abuts to retain said slide in a position notobstructing the entrance to said openings and against the other side ofwhich the latching member abuts to maintain the slide in a positionobstructing the entrances tor said openings, a spring urging said latchmember into a position aligned with said stop, said latching memberhaving a notched portion receiving the face end of said trigger wherebythe latching member is retracted from alignment with said stop whentrigger is depressed by the motor clamping screws upon insertion of thelatter in said openings, a second horizontal elongated slot in the sideof said housing, and means extended through said second slot andconnected to said latching means for movement of said latching means outof alignment with said stop and subsequent movement of said slide to aposition not obstructing the entrances to the openings.
